10) During the system calibration process, if the
«Re-zeroing is unsuccessful See service manual
Press YES to END» is displayed, turn the ignition
switch to OFF once and turn it to ON again, and
then read the DTC of airbag system. AB(diag)-31, OPERATION, Subaru Select Moni-
tor.>
When DTC is input, fix the fault and then perform
the system calibration. When DTC is not input,
check the seat and vehicle status and then perform
the system calibration again. SYSTEM CALIBRATION (REZEROING), OPERA-
TION, Subaru Select Monitor.>
NOTE:
When the re-zeroing is unsuccessful, there could
be occupant detection system failure or improper
seat and vehicle status. When the airbag warning
light illuminates, read the DTC of airbag system,
and perform the diagnosis referring to “List of Diag-
nostic Trouble Code.” ATION, Subaru Select Monitor.> 45, LIST, List of Diagnostic Trouble Code (DTC).>

IMPOSSIBLE
DETECTING CONDITION:
Defective harness connector
TROUBLE SYMPTOM:
Communication is impossible between the airbag
control module and the Subaru Select Monitor.
Refer to “Initial Communication Impossible” in the
DTC of the airbag system (diagnosis). AB(diag)-33, INSPECTION, Subaru Select Moni-
tor.>
2. WITHOUT DTC
DETECTING CONDITION:
•Defective combination meter
•Open circuit of harness
TROUBLE SYMPTOM:
•Airbag warning light remains on.
•“NO TROUBLE CODE” will be displayed on the
Subaru Select Monitor.
For detailed operation procedure, refer to “Airbag
Warning Light Failure”. bag Warning Light Failure.>
NOTE:
When the airbag warning light is OFF and “NO
TROUBLE CODE” is displayed on Subaru Select
Monitor, the system is in normal condition.
